I suspect high heteroscedasticity in this model. I suggest a White test and latter Log-Log model.

Just to take this funny nerd post at face value, I suspect the same. This is essentially what posters have been arguing is the case, in layman terms.

I would further suggest that even should a correlation be shown, that the findings would have no significance, given what we are actually interested in. For example, insurance agents (ties) are more successful than McDonald's fry guys (no ties), but this says nothing about whether high levels of achievement and tie wearing are at all correlated.

It really depends on the location. In some parts of the world, wearing a tie is more of a uniform and it has nothing to do with success. For some reason, Tokyo comes to mind as Japanese like to wear black suits and dark colored ties, ranging all the way from the company CEO to entry level office worker.

In many parts of the US, the business casual work environment has really taken over and big name CEOs (or former CEOs) like Bill Gates, Seve jobs and Mark Zuckerberg are rarely seen in ties, except on special occasions. Once again it is also a uniform in many industries even here in the US. What percentage of lawyers wear a tie? Probably a very high percentage. Are they all successful? I guess it really depends on your definition of sucess...

You can't simply conclude that wearing ties mean a man is successful. But it means that if the man wears ties a lot he must also wear suits a lot which might mean he has a high-powered job or he's simply required to wear it - not necessarily successful.

Hmmm, I think there is also a good argument that driving a nice car does make you more successful.

Here are two examples:

Imagine you work in Real Estate and drive around clients. I bet driving a nice car (like a new 5 series for example) will make you look more successful and accomplished. I bet that if you took two agents that have the same exact skill set, and one of them drives a newer BMW while the other drives a 10 year old Honda, that the one with the nicer car will get the first sale. Would you agree?

Here is another example: you pick up a girl you met for a first date...

I love this example! I use it myself I find it interesting as most people will want to do business with those that they perceive are successful.. even if its subconscious. but when you ask someone this very same question a lot of people will make up all kinds of interesting reasons why the Honda guy could be the better choice.

the reality of it is that an instant first impression is always made regardless. If the only information you had to decide which realtor was more successful was the cars they were standing next to I think its quite obvious that bmw guy wins every time. Besides id love to see 10yr old Honda guy showing million dollar + properties to clients driving them around in that pos!

I wouldn't feel comfortable having a realtor in a 10 year old beater I would automatically assume he wasn't very successful as if he/she were surely having a nice car to drive clients around in would be a top priority yes? Ill take bmw guy lol!
